Expert Front End Developer Needed for Long Term

Looking for a highly experienced front end developer with expertise in multiple frameworks and languages to help bring designs to life. No backend experience required. Ideally, the developer must have already experienced hundreds of UI challenges especially in cross-resolution builds and successfully resolved overcome such challenges. Please present your Git profiles / Codepens so I can at least get a sense of your experience. The initial project consists of developing front end for 3 web pages, for which desktop and mobile designs will be presented separately. Designs were created in Sketch. If proven reliable with reasonable pace, pricing and experience, constant work is guaranteed throughout the year. Thank you!
